8.2.3 One Channel Operation for Hot Trip Point up to 124°C

Figure 13 shows the TMP392 configured for one channel operation, with a single resistor to set the hot trip point

and hysteresis. Table 4 shows the possible resistor values and hysteresis values that may be used for one

channel applications.
